I want to compile a c file, but an error occurs after entering the compile command.
~$ gcc helloworld.c -o helloworld
fatal error: stdio.h: No such file or directory
compilation terminated.
I installed libc6-dev according to the method on the Internet
~$ sudo apt install libc6-dev
Then this error appeared

What should I do
I have debian, but I think this solution can help you. This is the new line I added to my /etc/apt/sources.list
deb http://ftp.it.debian.org/debian bullseye-updates main contrib non-free

I've recently learned that one can use apt to download sources and easily amend, re-build, and install the package locally from Cinnamon volume step and media keys.
# Download the sources
apt source cinnamon-settings-daemon
cd cinnamon-settings-daemon-4.4.0+tricia
# Then install the build dependencies
apt build-dep cinnamon-settings-daemon
#Then build from the modified sources
apt build
Install the modified deb file (again note the version string may differ for different Cinnamon versions)
apt deb ~/cinnamon-settings-daemon_4.4.0+tricia_amd64.deb
I now also want to be able to just download all packages needed for apt build-dep as for binary package install How to list/download the recursive dependencies of a debian package?. However, when I've tried to use --download-only and then install debs files, it resulted in several other files needed:
The following additional packages will be installed:
libarchive-cpio-perl libcupsfilters-dev libicu66:i386 libltdl-dev
libmail-sendmail-perl libpng-tools libpulse0:i386 libsys-hostname-long-perl
Even $ apt-cache depends --recurse --no-recommends --no-suggests --no-conflicts --no-breaks --no-replaces --no-enhances cinnamon-settings-daemon | grep "^\w" | sort -u does not list e.g. libarchive-cpio-perl and also --download-only when I tried to substitute empty dmkg status file ($(apt-config shell STATUS Dir::State::status)) and downloaded ~500 files, not ~100, that "additional" file(s) is(are) still missing.
Added 1:
I added --no-install-recommends to apt install debs and now only two i386 remained in additional not downloaded:
The following additional packages will be installed:
libicu66:i386 libpulse0:i386
Any idea what is so special about them? These are the only i386 mentioned, 1st one listed in apt cache above. 2nd not listed, so combining two deb sets is not a way to solve.
I downloaded debs with dpkg status file corresponding to a system with less packages installed than one where I tried to install later. I assumed it ensures all required are downloaded. However, as I received an answer after facing same issue with regular (not build, sources) packages, it is not so: https://unix.stackexchange.com/a/684975/446998. Additionally installed packages included some i386 architecture packages with corresponding amd64 packages among downloaded debs, so i386 required upgrade too when amd64 were installed as needed to be kept in sync.
I want to install ws-rtsp-proxy_1.8-4_armhf.deb in my armhf7 board
while doing this I got the error. But I have all the dependencies which I have attached below.
root#rt-work:~# apt-get install ./ws-rtsp-proxy_1.8-4_armhf.deb

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
ws-rtsp-proxy : Depends: libgcc1 (>= 1:3.5) but linaro-7.2-r2017.11 is installed
Depends: libssl1.0.0 (>= 1.0.0) but it is not installable
Depends: systemd but it is not installable
E: Unmet dependencies. Try using -f.
But libgcc and libssl1 are already there as you can see:
root#rt-work:~# dpkg --list | grep -i "libgcc1"
ii libgcc1 linaro-7.2-r2017.11 armhf GNU cc ands

How could I solve the issue?
Edit
I download the ws-rtsp-proxy_1.8-4_armhf.deb from this site-->https://streamedian.com/ and i try to install it in my armhf board. The deb i have downloaded is Raspbian 9.3(.deb)
or libgcc and libssl are already present in my rootfs
appear

I'm trying to install V4L2 on Ubuntu 10.04 (lucid) that require the xlibs-devinstalled. I tried: sudo apt-get install xlibs-dev but it returns:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package xlibs-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package xlibs-dev has no installation candidate
then I tried:
First attempt: attemp:sudo apt-get install xorg-dev;
Second attemp: sudo apt-get update and sudo apt-get upgrade;
All failed. same install xorg-dev,updated and upgraded my packages, can't to install the xlibs-dev library. how to fix this? thanks in advance.
The command
apt-cache search xlib dev
suggest you to
aptitude install libx11-dev
And your distribution might have V4L2. Consider installing the v4l2ucp package...
PS. There is no s letter in xlib because it is one library, not several!
I installed opencv2.3 on ubuntu by first adding the ppa and the doing apt-get install
$ sudo add-apt-repository ppa:gijzelaar/cuda
$ sudo add-apt-repository ppa:gijzelaar/opencv2.3
$ sudo apt-get update
$ sudo apt-get install libopencv-dev
I am developing on Eclipse and my programs work. I have this one problem though, while following an ebook. I cannot find the /opencv/samples folder in my system. I did a unix directory search to no avail.
Also, in Synaptic Package Manager I find that the opencv packages are not marked green, ie they're not installed. However I have written and executed opencv codes on my machine.
What is the reason for this?
It seems you have installed binary OpenCV package while the samples are (most likely) included only to source package.
